Notes:
- Some shortcuts do not work in earlier versions of the plugin. Update the plugin version to v1.1.1 by following the link /download/vectorscribe-download.html.
When dragging out a marquee:

“Shift” + “Option / Alt” adds corners to all applicable points on paths intersecting the marquee.

When mousing down on a corner:

“Space” hides the annotations.

“Option / Alt” shows the corner’s original (zero-radius) appearance [unless "Option / Alt" was held down before the click-down; see above]
